FHIR FHIRPath Function: checkModifiers

This page is part of FHIR FHIRPath (FHIR-specific extensions). Base spec lives at FHIRPath.

checkModifiers(modifier : string) : collection

For each element in the input collection, verifies that there are no modifying extensions defined other than the ones given by the modifier argument (comma-separated string). If the check passes, the input collection is returned. Otherwise, an error is thrown, including if modifier is empty.
